5 of' the parts. They are widely used in the automobile industry andparticularly in automobile bodymconstruction.- One specic use is betweenthe fender and the adjacent body portion.

Such strips include a web portion and a marginal bead portion. The webportion is adapted to be inserted between the two adjoining metal parts.The metal parts are secured together through this web porti-on. Thestrip is so positioned between the metal parts that the bead portionextends along and overlies the joint between the metal parts. The beadhas a finished outer surface so that it presents a neat finishedappearance. My invention relates to improvements in strips of this type.One object of my invention -is the provision of a strip of this 'naturewhich is inexpensive, which is waterproof, which isyieldinglycompressible and resilient, and which is adapted to seal thejoint between the two metal parts and further to seal itself adhesivelyacross said metal parts preventing the ingress of dirt or Water into thejoint between said parts.

A characteristicy of my invention is that the web width which isdisposed between the adjoining metal parts is impregnated with latexwhich forms a connective film filling the interstices of i the materialand extending in the form of a water proof envelope over the outersurface of the web. In addition, it renders the web compressible andresilient and it further seals the opposed surfaces of the web widthagainst the adjoining metal faces preventing the seepage of water intothe joint.

Other objects, advantages, and meritorious characteristics of myinvention will more fully appear from the following specification,appended claims, and accompanying drawing, wherein:

Figure 1 isa perspective of 'my improved welt partly unfolded to showthe structure,

Figure 2 is a cross sectional View transversely of the welt shown inFigure l, and

Figure 3 is a sectional View through a fragment of a body structureshowing the employment of my invention.

My improved anti-squeak strip is formed of va width of. webbing ofsuitable fibrous material.

I prefer to employ a loosely woven brous material such as jute webbing.'This material is impregnated with a suitable latex compound.

The latex compound is allowed to set to a tacky condition and the stripis then folded over a cord or the like, indicated as I0. This cord maybe est formed of twisted paper or any other suitable material. The stripis brought together over the' cord and the separate folds are pressedtogether. This operation results in the formation of a double thicknessof material i2 extending away from the cord in the form of a web.

As a result of the'impregnation with the latex compound and thecompressionl of the folds together the web portion l2 is thoroughlyimpregnated with the latex and the interstices thereof are filled withsuch compound.

The latex extends as a film between the two layers of the material. Itextends as a film over the outer surface of the web. It forms aresilient connective film enveloping the web.

A strip of finish fabric I4, such as'artiflcial leather or the like, isthen folded over the covered cord as shown. This finish strip isadhesively heldin place thereover and upon both sides of the web asillustrated. The latex compound which was used to impregnate the webadhesivelyV secures this strip in place. An additional layer of adhesivemay be used underneath said strip if found desirable. It is unnecessaryto employ any stitching or any other securing means in a construction ofthis character. Adhesive com# pound is sufiicient to secure the severalparts of n the finished article together.

The latex` compound is utilized in a sufficient quantity so that itrenders the web yieldingly compressible and resilient.

In the drawing the complete strip is illustrated as disposed betweenadjoining metal parts I6 and I8 which are held together by fasteningmeans 20. The stripv completely seals the joint between-such partsfilling the irregularities of the opposed surfaces of the parts. Inaddition, it seals itself against the adjoining surfaces of themetalparts. Along and adjacentvto the bead it is present in such an amountthat it forms a yielding cushionlike layer that fills the spaces betweenthe metal parts at the entrance to the joint. Should any water seep in,however, it vwill not penetrate suniciently to rust the metal parts orrot the fabric material as the two surfaces of the web portion aresealed against the opposed adjacent metal faces.

The impregnation of the web 'material and the. compression of the doublethickness thereof forms a web portion which possesses sufficientstiffness so .that it is self-supporting. It is stiiily selfsupportingso that itmay be readily inserted within relatively limited spacesbetween the metal parts, yet it is sufciently fiexible and compressibleto accurately conform to irregularities of the surfaces which itadjoins.

A suitable latex compoundl may be formed of 5,0 c. c. m'. of rubberlatex, 4 c. c. m. of saturated Burgundy pitch solution, and 20 drops ofNeo-` zone L.

'I'he amount of the saturated Burgundy pitch solution may be varied upto 6 c. c. m. with the amount of latex set forth above and the Neo' zoneL may be increased up to 60 drops in the f schedule' set forth above.

. layers being compressed together with the latex adhesively securingthem together and forming a permanently tacky moisture resisting iilmextending over each outer surface of the web and a film extendingbetween the two layers constituting the web and through the intersticesof the two layers, and a finish strip folded over the folded edge of theweb and adhesively secured thereto.

2. Ah anti-squeak strip comprising a loosely woven web width soimpregnated with a suitable latex compound as to form a latex coatingover 'the individual bers of the web material, said width of materialfolded lengthwise upon itself into a double thickness'web andcompressedv together, said latex compound adhesively securing the foldsof the material together and forming a film therebetween and a filmthereover and extending through the interstices of thematerial, a cordextending between the folds along the fold line, and a strip of hardsurfaced finish material folded over the folded edge of the web andadhesively secured thereto by the outer coating of latex on the webwidth, said web width containing sufficient latex characterized by beingnor- .mally tacky to render the same sufliciently stiff to beself-supporting while retaining yielding flexibility and resiliency.

3. An anti-squeak strip comprising two superimposed layers of looselywoven fibrous webbing impregnated throughout with a latex compoundforming a latex covering enclosing the individual fibers which make upthe webbing;` a cord extending along one linear margin of saidsuperimposed layers, said layers being compressed together and heldtogether by the latex compound with which the layers are impregnated,said latex compound extending between said layers and through theinterstices thereof to the outer surface of each layer rendering the twolayers and the individual fibers which make up the samewater-resisting', and rendering said two layers suiiiciently rigid to beself -supporting as a unitary structure, and a strip of finishingmaterial folded over said cord and adhesively secured to the oppositesurfaces of said superimposed layers.

4. A welt comprising a bead filler, a strip of loosely woven fabricimpregnated with a latex compound and folded over the bead filler so asto provide a bead at one edge of the welt with a leg projectingtherefrom, and a finish strip folded over said bead, said latex compoundadhesively securing said folds together and said finish st'rip to saidbead portion.

5. A welt comprising a bead portion, superimposed layers of looselywoven fabric impregnated with and adhesively secured together by a latexcompound and adhesively secured by the latex compound to the beadportion so as to pro vide a bead along one edge of the welt with a webprojecting therefrom, and a finish strip folded over the bead andadhesively secured thereto and to said layers.
